Morphological characterization of the leukocytes in circulating blood of the turtle (Phrynops hilarii)

The Phrynops hilarii specie of turtle has its characterization not well defined in the literature, it was proposed in this study the leukocyte characterization of the blood, stained by Leishman and analyzed under light and transmission electron microscope. It was not observe any cellular type with similar characteristics to neutrophils in mammalian group. We believed, based on the data obtained in this study that the heterophils have a morphofuncional analogy with another neutrophils belonged to mammalian group. This conclusion is being supported in many recent studies found in the literature.

Results of the GEP-ISFG collaborative study on an X-STR Decaplex

A collaborative work was carried out by the Spanish and Portuguese ISFG Working Group with a PCR multiplex for X chromosome STRs. Markers were selected among those described as polymorphic in humans and that have been used by some laboratories in forensics. Primers and various technical methods were investigated with the aim of optimizing a multiplex for the 10 selected X-STRs. Primer mix stock solutions were sent to the laboratories that were asked to analyse two female bloodstains, taking as reference the genetic profiles from 9947A, 9948 and NA3657 samples. In this work, we report the results obtained by 30 GEP-ISFG laboratories, using this Decaplex, as well as alternative technical conditions that also produced good results. © 2008 Elsevier B.V.

Avaliação crítica da legislação brasileira de sucos de fruta, com ênfase no suco de fruta pronto para beber

The aim of this work was to critically assess the Brazilian regulations on fruit juices, with emphasis on ready-to-drink fruit juice. According to the Brazilian regulations, bottled fruit juices must follow specific regulations. They should be in accordance with the definition and designation that identify them, with the quality parameters established, and especially, follow the Brazilian food labeling regulations. The Brazilian regulations on bottled fruit juices have some gaps that promote their misunderstanding and marketing of substandard juices. Frequent changes, divergent labeling regulations and inappropriate use of expressions on the label can also lead to misinterpretation. Food regulations need to be clear and updated frequently if they are to be known and followed. Additionally, their wide dissemination should contribute to informed choices when buying.

Uniconazole on mango floral induction cultivar 'Kent' at submedio são francisco region, Brazil

In order to provide efficient crop management which enables the scaling of the production of mango in semi-arid conditions and achieve a greater precision in the recommendation, evaluating the effect and the influence of uniconazole foliar spray, on the emission of vegetative flushes in the cultivar 'Kent', field tests were carried out in a productive orchard. Treatments tested were three uniconazole dosages, 500, 1,000 and 1,500 mg L-1, with one, two or three respective foliar sprayings. Another treatment with paclobutrazol was used at 2.0 g a.i./m of canopy diameter, with a single application via soil and a control (without spraying of plant growth regulators), where spreader-sticker was added and the pH was adjusted. With 30, 60 and 90 days after the first spraying of the flowering inducer the growth of branches were evaluated, as well as the percentage of flowering in all treatments after 120 days of first spraying. The sprayings started in the orchard after the emission of the second vegetative flush after pruning of production, through airassisted sprayer with flow rate of 1,000 L ha-1. The experimental design was done through randomized blocks with four replications, using three plants per plot. It was observed that paclobutrazol was significantly highlighted in relation to other treatments and that the uniconazole with one, two and three foliar sprayings presented inhibition of the vegetative growth in mango 'Kent' and showed, even at low proportions, signs of flowering.

The Poisson-exponential lifetime distribution

In this paper we proposed a new two-parameters lifetime distribution with increasing failure rate. The new distribution arises on a latent complementary risk problem base. The properties of the proposed distribution are discussed, including a formal proof of its probability density function and explicit algebraic formulae for its reliability and failure rate functions, quantiles and moments, including the mean and variance. A simple EM-type algorithm for iteratively computing maximum likelihood estimates is presented. The Fisher information matrix is derived analytically in order to obtaining the asymptotic covariance matrix. The methodology is illustrated on a real data set. © 2010 Elsevier B.V.

Bone apposition to laminin-1 coated implants: Histologic and 3D evaluation

Laminin-1 has been reported as one of the factors responsible for the nucleation of calcium phosphates and, in vitro, has been reported to selectively recruit osteoprogenitors. This article focused on its in vivo effects, and evaluated the effect of laminin-1 local application on osseointegration. Polished cylindrical hydroxyapatite implants were coated with laminin-1 (test) and the bone responses in the rabbit tibiae after 2 and 4 weeks were evaluated and compared to the non-coated implants (control). Before the samples were processed for histological sectioning, they were three-dimensionally analysed with micro computed tomography (μCT). Both evaluation methods were analysed with regards to bone area around the implant and bone to implant contact. From the histologic observation, new bone formation around the laminin-1 coated implant at 2 weeks seemed to have increased the amount of supporting bone around the implant, however, at 4 weeks, the two groups presented no notable differences. The two-dimensional and three-dimensional morphometric evaluation revealed that both histologic and three-dimensional analysis showed some tendency in favour of the test group implants, however there was no statistical significance between the test and control group results. © 2012 International Association of Oral and Maxillofacial Surgeons.

Physiological adaptations during endurance training below anaerobic threshold in rats

To assess the effects of continuous exercise training at intensities corresponding to 80 and 90 % of the lactate minimum test (LM), we evaluated antioxidant activity, hormone concentration, biochemical analyses and aerobic and anaerobic performance, as well as glycogen stores, during 12 weeks of swimming training in rats. One-hundred rats were separated into three groups: control (CG, n = 40), exercise at 80 (EG80, n = 30) and 90 % (EG90, n = 30) of LM. The training lasted 12 weeks, with sessions of 60 min/day, 6 days/week. The intensity was based at 80 and 90 % of the LM. The volume did not differ between training groups (Ẋ of EG80 = 52 ± 4 min; Ẋ of EG90 = 56 ± 2 min). The glycogen concentration (mg/100 mg) in the gastrocnemius increased after the training in EG80 (0.788 ± 0.118) and EG90 (0.795 ± 0.157) in comparison to the control (0.390 ± 0.132). The glycogen stores in the soleus enhanced after the training in EG90 (0.677 ± 0.230) in comparison to the control (0.343 ± 0.142). The aerobic performance increased by 43 and 34 % for EG80 and EG90, respectively, in relation to baseline. The antioxidant enzymes remain unchanged during the training. Creatine kinase (U/L) increased after 8 weeks in both groups (EG80 = 427.2 ± 97.4; EG90 = 641.1 ± 90.2) in relation to the control (246.9 ± 66.8), and corticosterone (ng/mL) increased after 12 weeks in EG90 (539 ± 54) in comparison to the control (362 ± 44). The continuous exercise at 80 and 90 % of the LM has a marked aerobic impact on endurance performance without significantly biomarkers changes compared to control. © 2013 Springer-Verlag Berlin Heidelberg.

Horse chestnut (Aesculus hippocastanum L.) starch: Basic physico-chemical characteristics and use as thermoplastic material

Starch isolated from non-edible Aesculus hippocastanum seeds was characterized and used for preparing starch-based materials. The apparent amylose content of the isolated starch was 33.1%. The size of starch granules ranged from 0.7 to 35 pm, and correlated with the shape of granules (spherical, oval and irregular). The chain length distribution profile of amylopectin showed two peaks, at polymerization degree (DP) of 12 and 41-43. Around 53% of branch unit chains had DP in the range of 11-20. A. hippocastanum starch displayed a typical C-type pattern and the maximum decomposition temperature was 317 degrees C.Thermoplastic starch (TPS) prepared from A. hippocastanum with glycerol and processed by melt blending exhibited adequate mechanical and thermal properties. In contrast, plasticized TPS with glycerol:malic acid (1:1) showed lower thermal stability and a pasty and sticky behavior, indicating that malic acid accelerates degradation of starch during processing.

The effects of body biometrics on cardiac measurements and description of cardiac anatomy were performed in red-tailed boas (Boa constrictor constrictor) (n = 29) using real-time B-mode ultrasonography. Statistical comparison of measured cardiac metrics according to sex and body measurements demonstrated no significant difference between sexes but a highly significant linear increase between body length and mass and all cardiac metrics.

"Will It Rain?" Activities Investigating Aerosol Hygroscopicity and Deliquescence

Climate change and its consequences seem to be increasingly evident in our daily lives. However, is it possible for students to identify a relationship between these large-scale events and the chemistry taught in the classroom? The aim of the present work is to demonstrate that chemistry can assist in elucidating important environmental issues. Simple experiments are used to demonstrate the mechanism of cloud formation, as well as the influence of anthropogenic and natural emissions on the precipitation process. The experiments presented show the way in which particles of soluble salts commonly found in the environment can absorb water in the atmosphere and influence cloud formation.
